Abstract: In order to study the state of existence of microfilaments in phaneroplasmodium of Fuligo septica and realize the purpose of studying phaneroplasmodium from the nucleus level,through the cultivation and the fluorescence staining of phaneroplasmodium of Fuligo septica,it was found that there was microfilament existed in plasmodium.In further research,it was found that the microfilament presented the border of gel-like ectoplasm and inner more fluid endoplasm of veins of plasmodium,which provided strong evidence for microfilament participated in the protoplasm movement in myxomycetes.It is concluded that the microfilament may be an important component of the cluster network in the phaneroplasmodium.
